METHODS: From an administrative database of 48,435 adult patients who underwent noncardiac surgery from 2011 to 2014 at a single, large urban academic institution, multivariable zero-truncated negative binomial regression analyses controlling for age, sex, medical comorbidities, and surgical type were performed to assess whether preoperative exposure to antidepressant or antianxiety medication use was associated with postoperative hospital length of stay.
RESULTS: There were 5111 (10.5%) patients on antidepressants and 4912 (10.1%) patients on antianxiety medications. The median length of stay was 3 days (interquartile range = 2–6). After controlling for confounding variables, preoperative antidepressant medication was associated with increased length of stay with an incidence rate ratio of 1.04 (99% confidence interval, 1.0–1.08, P < .001) and antianxiety medication with an incidence rate ratio of 1.1 (99% confidence interval, 1.06–1.14; P < .001).
CONCLUSIONS: The association between antidepressants or antianxiety medications and increased postoperative length of stay suggests that these patients may require greater attention in the perioperative period to hasten recovery, which may involve integrating preoperative counseling, postoperative psychiatric consults, or holistic recovery approaches into enhanced recovery protocols.
KEY POINTS
- Question: What is the relationship between preoperative antidepressant and antianxiety medication and postoperative hospital length of stay?
- Findings: Preoperative antidepressant and antianxiety medications are associated with an increased postoperative hospital length of stay.
- Meaning: Either due to underlying psychiatric disease or medication effects, patients on preoperative antidepressant and antianxiety medication stay in the hospital longer after surgery and may require greater attention to hasten recovery.
